DFM will do it nicely. I believe you can also use NMC (netapp management console). DFM is a GREAT tool that I wouldnt be without if
I managed NetApp controllers. It does reporting too and all sort of things, I recommend reading up on DFM.
DFM is also referred to as Operations Manager (OM). Actually I think the more current name is OM and not DFM.
